The Detroit Pistons had their way with Minnesota's struggling defense, hitting 14 of 29 3-pointers in a 117-90 victory as the Wolves lost for the seventh time in the last eight games. Fans booed early in the fourth quarter as the Pistons finished off a 31-10 run that sent most toward the exits.
The Timberwolves, mired in a 12-year playoff drought, haven't won at home since Nov. 17.
"We can accept making mistakes and [when we] don't make shots," Rubio said after the game. "Playing with no heart, with no desire, it's just awful. Right now, it's just bad.
"And it seems like we didn't care."
A "very concerned" Thibodeau said "everything is on the table" as he looks to fix things, including lineup changes for the 6-17 Wolves, who next face the Golden State Warriors on Sunday.
"I'm going to keep coming. I don't go away," Thibodeau vowed. "I'm going to look at everything, re-examine. Something's being missed. It's got to change.
"Something is not right. We have to find the answer to that."
